Savannah vs Engels

Informations

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800–3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha.

Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season; they are associated with several types of biomes, and are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area.

Friedrich Engels ( ENG-(g)əlz, German: [ˈfʁiːdʁɪç ˈʔɛŋl̩s]), sometimes anglicised as Frederick Engels (28 November 1820 – 5 August 1895), was a German philosopher, historian, political scientist and revolutionary socialist. He was also a businessman, journalist and political activist, whose father was an owner of large textile factories in Salford (Greater Manchester, England) and Barmen, Prussia (now Wuppertal, Germany).Engels developed what is now known as Marxism together with Karl Marx. In 1845, he published The Condition of the Working Class in England, based on personal observations and research in English cities. In 1848, Engels co-authored The Communist Manifesto with Marx and also authored and co-authored (primarily with Marx) many other works.

Later, Engels supported Marx financially, allowing him to do research and write Das Kapital. After Marx's death, Engels edited the second and third volumes of Das Kapital. Additionally, Engels organised Marx's notes on the Theories of Surplus Value which were later published as the "fourth volume" of Das Kapital. In 1884, he published The Origin of the Family, Private Property and the State on the basis of Marx's ethnographic research. On 5 August 1895, aged 74, Engels died of laryngeal cancer in London. Following cremation, his ashes were scattered off Beachy Head, near Eastbourne.
